Android Navigation - Preview Unavailable 해결하기

Android Navigation 구성요소 중 navigation 리소스를 생성하면 'Preview UnavaUnavailable' 문구를 볼 수 있습니다.

 

nav_graph.xml

<?xml version="1.0" encoding="utf-8"?>
<navigation xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/nav_graph"
    app:startDestination="@id/nav_home">
    <fragment
        android:id="@+id/nav_home"
        android:name="com.ggu.motion.ui.HomeFragment"
        android:label="HomeFragment">
        <action
            android:id="@+id/action_nav_home_to_nav_submit"
            app:destination="@id/nav_submit" />
    </fragment>

    <fragment
        android:id="@+id/nav_submit"
        android:name="com.ggu.motion.ui.SubmitFragment"
        android:label="SubmitFragment"/>
</navigation>

Preview

 

<fragment /> 에서 tools:layout="{레이아웃 id}" 를 추가해주면 Preview를 정상적으로 확인할 수 있습니다.

<fragment
        android:id="@+id/nav_submit"
        android:name="com.ggu.motion.ui.SubmitFragment"
        android:label="SubmitFragment"
        tools:layout="@layout/fragment_submit"/>

Preview

 

감사합니다.
